. Application 2 cur s.

invention relates to bath tubs, land more particularly to a bath tubthat is adapted to be usedby physically handicapped individuals. Anobject of the invention is to provide'a bath tublhaving meanswhichwillraise the tub to a occupant would prevent their operation ofthe raising and lowering means.

With the above and other objects and advantages in view, the inventionconsists of the novel details of construction, arrangement andcombination, of parts more fully hereinafter de-" scribed, claimed andillustratedin the accompanying'dr'awings in which:

Figure 1 is an elevational view of an embodiment of the invention; I

Figure 2 is a sectional view on the line 2-2 of Figure 1 in bathingposition;

Figure .3 is an end view thereof;

Figure 4 is a sectional view similar to Figure 3 with the bath tub invertical occupant receiving position; t

Figure 5 is a bottom plan view thereof;

Figure 6 is a sectional view on the line 6-6 of Figure 1;

Figure '1 is an elevational view of the tub in occupant receivingposition;

Figure 8 is a rear view of Figure 7;

Figure 9 is an end view of the end opposite to that shown in Figure 3and Figure 10 is a side elevational view of the side opposite to thatshown in Figure 1. 1

Referring more in detail to the drawings, the

reference numeral 20 comprises the supporting base or standfor thetub'2|, and comprises two horizontally disposed parallel substantiallyU-shaped members 22 and 23 respectively which are connected together attheir respective bases in spaced relation to each other by the verticalplate member 24, such connection being made by use of suitable fasteningmeans 25.

Connected to the ends of the members 22 and 23 by welding or the like isa vertically disposed U-shaped member 26, which spaces the members 22and .23 in the same manner as the member 24.

Secured to the center of the base of the member '26. is a bearing member21, and together with the'bearing member 28, secured to the rear ofrrvo'rnn BATHTUB John WrDavis, El Monte, Calif.

the member .24, centrally thereof at the bottom thereof,formsfjournalling means forthe screw operating rod 29, which extendsbeyond the plate 24 bymeans of theopening 30, and has a hand operatedwheel3| thereon for the turning of'the screw, as will be laterdescribed. A nut 32jisjkeyed to the oppositeend of the rod 29 and anut3,3 is positionedon'the outer side of the bearing28 and keyed thereto asis nut 32. Mountedon the rod v29 is the travelling nut 34 which iscaused to travel on the rod upon rotation of the-hand1 wheel 3|. Thenut34 is provided withan apertured ear 35 which is con-a nected to thelinks ,or arms36by a pivot pin 31. The arms are'parallelfto each therand spaced from each. other atone end lby the ear 35 and at the otherend by the depending projection 38 to which the ,arms are'connectedby apivot'pin 36,];Th'e projection 38 isformed integral with the head 40providing a T shaped structure which is slidably mounted'on the bottomof thetub 2| by means of parallel relatively spaced guide tracks 4|,which are secured to the bottom of the tub 20.

Secured to the members 22 and 23, inwardly of and adjacent to the member26, by welding or the like, is another u-shaped member 42 which carriesthe guide rod 43 which is slidably mounted in the alined elongated slots44 in the arms 36 for the guiding thereofduring the raising and loweringof the tub 2|.

In operation, the hand Wheel 3| is rotated to cause the tub to assume avertical position, and then a handicapped person can back into the tuband grasp the hand rails 45 on the upper edge of the tub and holdthemselves in the tub until the hand wheel is rotated in the oppositedirection to move the tub downwardly to a horizontal position for use inbathing.

The tub 2| is provided with a combined inlet and outlet 46 in the bottomthereof, which communicates with combined drain and supply pipe 41. Thedrain may be placed at either side of the tub, but for purposes ofillustration, the drain pipe in this instance will be designated as 48,having the hand operated valve 49 connected to the pipe 48 at the upperend thereof, and by a coupling 5|] and nut 5| to the drain end of thepipe 41. The nut 52 for joining the coupling 50 to the valve 49 isloosely mounted in the forked end ofan arm 53 which is secured to oneside of the member 26, and to the valve 49. Thus by operation of thehand wheel 54, water can be drained from the tub 2|, and the valve isconnected to pipe 48 by the usual connection 55.

The supply pipe 56 is connected to the hand operated valve 57 by theusual connection 58, and the valve 57 is connected to the opposite endof pipe 41 by a coupling 59 and nut 60. The nut'6l for joinin thecoupling 59 to the valve -51 is loosely mounted in the forked end of anarm 62 which is secured to the opposite side of the member 26 to that ofthe nut 52, and t valve 57 in like manner. By operation of the handwheel 63, water can be supplied to the tub for bathing purposes. Thepipe il, together with the couplings 50 and 59 provide the pivot meansfor the tub during the raising and lowering thereof means previouslydescribed.

Secured inwardly of the tub, by fasteners 64, is a shelf or compartment65 which is adapted to hold soap or other bath supply accessories,access being gained thereto by means of an opening 66 in the side of thetub, as shown in Figure 10.

Thus means has been provided for supplying water to the tub, anddraining water therefrom, and it is believed that from the foregoing,descrip tion, the operation and constructionof the tub will be apparentto those skilled in the art.

It is also to be understood that changesin the minor detailsofconstruction', arrangement and combination of parts may be resortedto, provided they fall within the spirit of the inventio andthe scope ofthe appended claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letter'sPatent is:

1. In a bath tub, the combination which comprises a bath tubstand, abathtub positioned on said stand with one end thereof projecting beyondthe associated end of thestand, means pivotally mounting said tub on theend of the stand at a point spaced from the projecting end of the tubwhereby when tilted, the tub is positioned substantially vertical withthe open upper surface extended outwardly to facilitate the entrance ofan invalid into the tub, and operating means for actuating the tub froma vertical to a horizontal position with an invalid therein.

2. In a bath tub, the combination which comprises a bath tub stand, abath tub positioned on said stand with one end thereof projecting beyondthe associated end of the stand, means pivotally mounting said tub onthe end of the stand at a point spaced from the projecting end of thetub whereby when tilted, the tub is positioned substantially verticalwith the open upper surface extended outwardly to facilitate theentrance of an invalid into the tub, a threaded rod rotatably mountedand angularly positioned in the stand, a hand wheel on the outer end ofthe threaded rod for rotating the same, a follower having an upwardlyextended ear threaded on the shaft, a link having an elongated slottherein pivotally mounted on the ear on the upper side of the follower,a tube with a slot in the undersurface mounted on the lower side of thebath tub, a slider slidably mounted in the tube having a projectionextending through the slot thereof, means pivotally mounting the end ofthe link opposite to the end mounted on the ear of the follower on theprojection of the slider, and friction means on the threaded rod forpreventing longitudinal movement thereof as it is rotated.
